'Be it known that I, Gnome GORDON Mus TED, a subject'of therKingof Great Britain and Ireland and the lsleo fMan, residing 3 at 721 Dumbarton Road, Partick, Glasgow, Scotland, have invented new and useful Clamps, of which the following is'a' specification; x I

- This invention hasreference to and com prises improvements -ini and relating to clamps and the like and particularly 're-;

. of the usual wire binding. Itis alsok suitable for joining end to end fiexible'tubing and'is also suitable for use in a -temporary repair, that is, should a tube leak or burst I it is only necessary to'cover the leak, with a suitable pad or plug'andfthen' to bind same with this clamp. a i i Flexible tubes,ffor use in connection with which this clamp is' particularly suitable,

are sometimes well worn, 'and -idist'orted and it ,is 'diflicultt'o get the jaws of the, clamp tight enoughfto effectively-close afleak.

'lheobject of this invention is to 'over come this difficulty and at the same time improve the construction of the clamp.

According to this invention the interio'r'of thej'aws are provided with a springplate or plateswhich mayo consist ,offa blade spring pivoted or otherwise secured to the inside surface of the jaw; Or,: if desired.

, bent i inwards ti I form the spring plates. The flanges or lugs of the one jawyagainst which the end of the tightening screw 0 'er ats'gis preferably ofhBok-Iike shape; ile

g formed with a 'hook-likef end adapted to embrace-the one lugwhile the plate may be hinged-to the otherlugof the-same jaw.

A screw 10 formed with a suitable head 11 works through a screwed hole tormedin the lug 6 hen this clamp is mountedupon afiexible tube or the-like the plate lies between the lugs 6 and 7 with the end of the screw 10 bearing againstsamea It will be readily understood. that the clamp jaws l and 2 are tightened on to the. tube y forcing pertiby m an tthe screw 10, the lugs 6 and "7.

In order that the tube may be gripped evenly and effectively, particularly when the tube is well wornt or. :li stc 1:-tec l,v a springor compensation plate 12 is secured to the inside surface otqone' -otthe jaws preferably by means of. rivets 13., q

Togremovethe clamp the screw 10 is run backwards: then the plate 8 swung upwards ontl 1epini9.
